Stripping device for rubber wheel on pickup roller of printer

Abstract

The invention discloses a stripping device for a rubber wheel on a pickup roller of a printer. The striping device for the rubber wheel on the pickup roller of the printer comprises a first connectingshaft, wherein a first baffle plate is formed at the other end of the first connecting shaft; a mandrel which is concentric with the first connecting shaft is formed on the first baffle plate; a plurality of dovetail grooves are formed in the outer wall of the mandrel; a rubber outer wheel is formed on the mandrel in a sleeving manner; a plurality of dovetail-shaped clamping strips are formed onthe inner wall of the rubber outer wheel, and are inserted in the dovetail grooves; a rectangular hole which penetrates through a side end surface of a fulcrum shaft is formed in a side end surface ofthe mandrel; the side end surface of the mandrel is abutted against a second baffle plate; a rectangular inserting strip is formed on a side end surface of the second baffle plate; the rectangular inserting strip is inserted in the rectangular hole of the mandrel, and a double-screw bolt is formed; the side end surface, which is exposed out of the fulcrum shaft, of the double-screw bolt is in screwed connection with a nut; and a second connecting shaft is formed on the other side end surface of the second baffle plate. The rubber wheel is changed conveniently, a rotating shaft with a gear onthe pickup roller does not need to be scraped, the rotating shaft can still be used, and thus, the utilization rate of resources is increased effectively.

Description

Technical field: [0001] The invention relates to the technical field of printer accessories, in particular to a peeling device for a rubber wheel on a printer pickup wheel. Background technique: [0002] The pickup roller is an important component of the printer. The existing pickup rollers generally consist of a rotating shaft and a rubber wheel body inserted on the rotating shaft. The general rubber wheel body is fixed on the rotating shaft by pasting to prevent the rubber wheel body from There is relative rotation with the rotating shaft, and the rubber wheel body is easy to age, and the fixed rubber wheel body is not easy to peel off from the rotating shaft, so a corresponding device is needed to peel off the rubber wheel body so that the rotating shaft can be recycled and reused. Invention content: [0003] The purpose of the present invention is to address the deficiencies in the prior art, and provides a device for peeling off the rubber wheel on the pickup roller o...
